Specification of Letters Patent.

Application filed June 19, 1907.

Serial No. 379,708.,

To all whom it may concern. 7

Be it known that I, JULIUs O. FoRKER, a citizen of the United States, residing in the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Transmission Apparatus, of which the following is a specification.

This invention relates to power transmitting mechanism and is especially designed. for using the driving or rear wheels of a-motor vehicle for driving machinery of any desired nature. 1

The object of the invention is to provide transmission mechanism whereby the rear or driving wheels of a motor vehicle can be placed thereon without in any way altering the motor vehicle and the ower from the driving of such wheels will e a plied toa power transmission member suc as a belt pulley. I

In the accompanying drawing illustrating one embodiment of my invention, Figure MS a side elevation of the device and of a motor vehicle in operative position thereon. Fig. 2 is a plan view of the transmission mechanism; and Fig. 3 shows a form of brake.

The device is preferably placed in or beneath the floor where the motor vehicle can be run, and is provided with suitable pulleys or wheels for engaging the tire or rim of the motor vehicle for sustaining the weight thereof and the frictional engagement of which when driven by the motor of the vehicle, will cause rotation of the pulle s on wheels. The ulleys are preferably p aced below the levelof the floor, and arranged in two pairs, one on each side a shortdistance removed to sustain the weight of the wheels and car thereon. In the construction illustrated in Fig. 2', a pair of wheels or pulleys 5 and 6 are rotataoly arranged in alinement a suitable distance apart and with their axes level," to reeeive one of the drivin wheels 8 of a motor vehicle, denoted generally by M. These pulleys preferably have then rims grooved at 9 and 10 as illustrated, to receive the usual term of inflated tires. On the opposite side, are a pair of similar pulleys 1i and 12 that are similarly placed to receive the other driving wheel of the motor vehicle, not. shown. The ulleys 9 and 11 are preferably secured to a shaft 13 that may be supported at each end in a beam 15'extending across between joists l6 and 17 of the floor 18; the

latter being provided with an o ening 19 above the four grooved pulleys. he other end of the shaft 13 is supported in a similar beam 20; and these two beams also form bearings for another shaft 21 to which is secured the two pulleys 11 and 12. A suitable transmission member, suchas a belt 'ulley,. .is connected to be driven from both 0 these two shafts 13 and 21. In the construction illustrated the two shafts-are also rotatably supported by cross beams 22 and 23, and

between these are mounted gears 24 and 25,,

of the transmission mechanism, a suitable brake is applied, The shaft 13 is shown as rovided with a band pulley 33, and a brake lever 34 is loosely pivoted on this shaft. A brake band 35 has one end secured to the lever34 and its other end to a stationary pin 36 connected with the beam '28, the band 35 passing around the drum 33. By shifting the lever the band 35 will be caused to tightly grip the drum 33 and prevent rotation of the shaft 13, and consequently of the other shaft through the gears.

in the operation of the device, the grooved pulleys bemg set a short distance beneath the floor 18, in the opening 19, the car M is backed so that the rear wheels will run on to these four grooved pulleys, resting thereon as illustrated in Fig.- 1. d Then the motor is operated, and the rotation of the rear wheels .will revolve the four grooved pulleys, and

consequently through the two gears the belt pulley 31 will be driven. By this means it is seen that it is absolutely unnecessary to make any chan e in the construction or arrangement of tie motor vehicle, but it is simply run on to the grooved pulleys and then the rear wheels are operated from the motor in the same manner as if the vehicle was runnin on the road.

if desire an electric generatorEean be coupled direct to the shaft 29, and be driven by the transmission apparatus from the motor of the car, to furnish an electric current for lighting purposes or for power.

When it is desired to run the cared from and the transmission device, the brake lever is swung to arrest the movement of the pulleys,

when the car can be runforward up on to the same time, no extra space is needed as the The brake lever 34 -has'a socket joint-at 37 wherzlya$ the handle portion can be removed not project above the floor 18. This will permit a trap tobe placed in the floor at t e opening 19 to close the same, when the apparatus is'not in use.

The transmission device is of especial advantage for use in a country place remote from fire extinguishing apparatus, as the belt can be connected with a pum or a pump could be connected direct with tiie shaft 29, in fplace ofthe electric generator E. Upon a re occurring inthe garage or a house or building in the vicinity, a car can be quickly run on the transmission rollers and the pump be brought at once into use, and a stream of water furnished to extinguish the fire. The motor cars in use frequently being plroiiided motors from forty to sixty a heavy stream of water could be thrown by the pump that could be of great service to put out a fire, and could be forced through a line of hose of considerable length.

Thus the a paratus takes the place of a fire engine, an could be brought into use in even lesstifne than it, would take to brin a fire apparatus to the place where the e occurred and .put it into operation. At the transmission device can be placed in the floor, and the pump also. v

Having described my invention what I claimis: j

In combination, a floor for supporting an automobile and having an aperture therein, a pair of pulleys supported beneath said floor and adjacent said aperture and adapted to support an automobile drive wheel and be rotated by said wheel, mechanism connected to said pulleys to be driven thereby, a brake for said pulleys, whereby they may beheld against rotation and said vehicle driven off of and on to the latter, an operating lever for said brake extending upwardly through said aperture and above said floor and detachable from said brake, whereby the aperture in said floor may be closed when said, pulleys and mechanism are not in use.
